Schubert Calculus via Hasse-Schmidt Derivations
Letterio Gatto
A natural Hasse-Schmidt derivation on the exterior algebra of a free module realizes the (small quantum) cohomology ring of the grassmannian $G_k(\CC^n)$ as a ring of operators on…

The Algebra of Schubert Calculus
Letterio Gatto
A flexible unified framework for both classical and quantum Schubert calculus is proposed. It is based on a natural combinatorial approach relying on the Hasse-Schmidt extension of…

A geometric interpretation and a new proof of a relation by Cornalba and Harris
Eduardo Esteves, Letterio Gatto
In the 80's M. Cornalba and J. Harris discovered a relation among the Hodge class and the boundary classes in the Picard group with rational coefficients of the moduli space of sta…
